Figure 2: Dirichlet-weighted diet proportion by weight of Pacific hake intraspecific predation by predator hake age and prey hake age for three periods: all years in the dataset, 1991-1999, and the acoustic trawl survey from 2005-2019.

Figure 4: Spawning stock biomass (mt), total biomass (mt), and recruitment (n) for Pacific hake from CEATTLE run in single-species mode with no predation, with the estimate of mean cannibalism, and the Stock Synthesis 3.0 run from the 2020 stock assessment.

Figure 6: Mean and standard deviation of numbers-at-age from CEATTLE run in single-secies mode with no predation, with the estimate of mean cannibalism, and the Stock Synthesis 3.0 run from the 2020 stock assessment.
Figure 7: Spawning stock biomass (mt), total biomass (mt), and recruitment (n) for Pacific hake from CEATTLE run with the estimate of mean cannibalism for the entire period, in single-species mode with no predation, for 1988-1999 with the estimate of mean cannibalism for that period, and for 2005-2019 with the estimate of mean cannibalism for that period.
Figure 8: Residual (M1) and predation (M2) mortality by age and year for CEATTLE run with the estimate of mean cannibalism for the entire period, for 1988-1999 with the estimate of mean cannibalism for that period, and for 2005-2019 with the estimate of mean cannibalism for that period.
